*
* In this subroutine we provide information about
* the function. The user configurable information
* consists of the following:
*
* descr Text description of the function
*
* num_args Required number of arguments
*
* axis_inheritance Type of axis for the result
* ( CUSTOM, IMPLIED_BY_ARGS, NORMAL, ABSTRACT )
* CUSTOM - user defined axis
* IMPLIED_BY_ARGS - same axis as the incoming argument
* NORMAL - the result is normal to this axis
* ABSTRACT - an axis which only has index values
*
* piecemeal_ok For memory optimization:
* axes where calculation may be performed piecemeal
* ( YES, NO )
*
*
* For each argument we provide the following information:
*
* name Text name for an argument
*
* unit Text units for an argument
*
* desc Text description of an argument
*
* axis_influence Are this argument's axes the same as the result grid?
* ( YES, NO )
*
* axis_extend How much does Ferret need to extend arg limits relative to result
