Summary

0000595: IMPLEMENTED: 4-parameter and 5-parameter logistic fitting

Description

Five fitting functions:
* LogisticFit4 - implements 4PL (four parameter logistic) fitting
* LogisticFit5 - implements 5PL (five parameter logistic) fitting
* LogisticFit4EC - implements 4PL (four parameter logistic) fitting with equality constraints
* LogisticFit5EC - implements 5PL (five parameter logistic) fitting with equality constraints
* LogisticFit45X - "expert" functions which implements 4PL and 5PL (depending on control flags) and allows better control of fitting process.

Two function to calculate 4PL/5PL model:
* LogisticCalc4 - to calculate 4PL model with correct handling of degenerate cases
* LogisticCalc5 - to calculate 5PL model with correct handling of degenerate cases
