[boost] New Feature, MathString.

Hi. My name is Jacob and i am new here.i have idea for new feature in boost. Actually i write a little library whitch name MathString. As you see by name the library will be calcule Row's from string. But it's not all. I was write a interface which add own Mathematical functions for row and variables. If you accept my idea i will send whole code. Code for example MathString test("sqrt(x,2)"); test.LinkFunction(&sqrt,"sqrt"); test.pushVariable("x",4); cout<<test.getResluts(); This code will be return 2 (as you know root with level 2 of 4 equals 2)
