minimax remez function

Based on this:

http://www.math.unipd.it/~alvise/CS_2008/APPROSSIMAZIONE_2009/MFILES/Remez.pdf

Please find attached remez.mcd and remeztest (simple test harness).

Not exhaustively tested but seems to work for me although I do get some errors with high order polynomial approximation.

Parameters:

F: function to be approximated

a: low limit of x range over which F is to be approximated

b: high limit ditto

n: order of polynomial

convergence limit: e.g. if 0.01 will stop iterating when error in approximation is within 1% of error in previous iteration

returns approximating polynomial coefficients c0, c1, ..., cn, maximum error in approximation

Any comments, improvements welcome.
