 *  This routine is part of the General Astrodynamics Library  
 *
 *  Description:
 *
 *     This routine copies the source string s2 to s1, then trims white-space
 *     from the beginning and end of the string. If the resultant string
 *     length is less than l then spaces are added on the right hand side 
 *     to bring the string to length l. If the resultant string length is 
 *     greater than l then the left-most l characters of the resultant
 *     string are returned in s1.
 *  
 *  Status: 
 *  
 *     String manipulation routine  
 *  
 *  Given:  
 *
 *     *s1             c[]          Target string
 *     *s2             c[]          Source string 
 *     l                i           Required target length
 *  
 *  Returned:  
 *  
 *     *gal_justl      *c           Pointer to the start of the target string
 *  
 *  Notes:  
 *
 *  1) The target string s1 must be at least the same length as the source 
 *     string s2.
 *
 *  Called:
 *
 *     gal_padr                     Pad string on right with spaces
 *     gal_trim                     Trim white-space from beginning and end of string
