// Function : TC_CompareStrings
// Purpose : Compare two strings, returning a negative value if the
// 1st string is less than the 2nd string, returning a
// positive value if the 1st string is greater than the
// 2nd string, and returning a 0 if both strings are the
// same. This function correctly handles alphanumeric
// strings in the form "xxx[nnn]" or "xxx(nnn)". For
// example, the sort order ( "A[1]", "A[11]", "A[2]" )
// results from a generic string compare function, while
// the sort order ( "A[1]", "A[2]", "A[11]" ) results from
// this compare function.
