## Detailed Description

### template<class T_>
struct osgParticle::range< T_ >

A simple struct template useful to store ranges of values as min/max pairs.

This struct template helps storing min/max ranges for values of any kind; class `T_` is the type of values to be stored, and it must support operations `T_ + T_`, `T_ - T_`, and `T_ * float`, otherwise the `get_random()` method will not compile. This struct could be extended to customize the random number generator (now it uses only `std::rand()`).
