	@class spell
	@abstract  Handles spell checking for email messages. Give it all necessary data and it handles the rest. All class params are 
	private unless an OOP style access function is provided.
	@param $max_suggest (int) maximum number is suggestions to show in a combobox
	@param $spell_svc (object) the spell service access class, a dummy module if pspell is not compiled in
	@param $can_spell (boolean) This is picked up from the spell service module, a dummy module will report False. Read Only, Access with ->get_can_spell()
	@param $sp_feed_type (defined integer) SP_FEED_UNKNOWN or SP_FEED_WORDS or SP_FEED_LINES, defined in file class.spell_struct
	@param $pspell_link (int) a pointer kind of thing you get when you create a new pspell dictionary link.
	@param $my_validator (object of type phpgwapi.validator) used to help decide what words to not bother spellchecking, like URLs.
	@param $widgets (object of type html_widgets)
	@param $user_lang (string) obtained from "phpgw_info", used when creating the pspell disctionary link. Read Only, Access with ->get_user_lang()
	@param $reject_reason (string) when this class decides a word is not worth checking, it fills this with the reason, ex. "do not check URLs"
	@param $subject (string) use OOP access functions ->set_subject and ->get_subject.
	@param $preserve_tokens (array) Scheduled For Depreciation, but still used. A list of GPC vars we typically want to preserve 
			thru the spellchecking process. However, it is too limiting to had a hard-coded list, need to allow more flexibility.
	@param $preserve_vars (array) use OOP access functions ->set_preserve_var and ->get_preserve_vars. Currently, 
			you can set any vars you want, but only those in the $preserve_tokens will be preserved as hiddenvars. NEEDS FIXING. 
	@param $body_orig  string use OOP access functions ->set_body_orig and ->get_body_orig.
			This is record of the original message before any spell check changes.
	@param $body_display  (PRIVATE) string ACCESS ONLY use OOP access functions  ->get_body_display.
			Scheduled for depreciation because the function "prep_body_display" directly returns this data and 
			there us no readon to keep it stored in this param. "prep_body_display" is quite useful, do not 
			limit it by bounding it to this param.
	@param THERE ARE MORE...
	@discussion  Provide this class with any of the above vars that you have. Subject and Body will be 
	spellchecked, but the other data is needed because this class handles the rest of the logic from spell 
	checking, to user review of spellcheck, to applying the users choices to the body, only then is the 
	message handed off to another object, either class send for sending, or class compose if the user wants to 
	edit the text some more. Calling process MUST set any vars it wants preserved through the spellcheck 
	process, they will be put in the spellcheck page form.

		@discussion Spell check is called from class.bosend, where the compose form gets submitted. 
		If the spellcheck button was pressed, then class.bosend creates an object of this class to handle the 
		spell checking. When the user submits the spellcheck form, the desired misspelled words will 
		be replaced and then this class invokes class.bocompose to take the user back to the compose form 
		with the corrected body text. From there the user may click send which submits the form to 
		class.bosend. Therefor any send related GPC vars that the compose form had when it was submitted 
		for spellchecking must be put back in the compose form after spellchecking so that class.bosend 
		gets the information it needs, the same information it would have gotten had a spell check not 
		occurred. Certain vars will be passed in the URL, these are sort, order, start, the msgball or 
		fldball, and fwd_proc are all passed in the URL that is the form "action". Other vars have their 
		own special requirements, these are body and subject vars, because they will be spellchecked. 
		All other vars that need to be preserved use this function to set their data. These var names 
		are enumerated in $this->preserve_tokens[] array, so that one code loop thru these tokens can 
		handle all the necessary vars to be preserved, such as in function "commit_preserve_vars_to_form". 
		Note that when class.bosend gets the submitted compose form and determines it needs to be directed 
		to this class for spellchecking, class.bosend MUST USE THE SET_* CODE in this class to set 
		any vars that class.bosend thinks should be saved. Class spell does not grab these vars, the calling 
		process must use the OOP style access methods to set them. Only then will this class be able to preserve
