pptools 0.8.1: *added GPL headers to each files; *created "pptools.lsm" description file; *created an INSTALL file; *added COPYING, AUTHOR, TODO files; pptools 0.8: *RLC solver is now fully C++; *added missing initial conditions to the RLC solver; *better color coding solver; *better help file (talks about almost every aspects); *fixed the rectangular coil inductance (it now contains all the coefficients, with interpolations where necessary); pptools 0.7: *added the begining of a help file in the "About" tab; *added a "refresh" call to the inductance panel every time the user activates the tabs -> the correct number of fields is displayed on the inductance panel; *better code modularization for the management of equations; *now, every equation can be solved by a Newton's method (or another one if re-defining the solver); *solver for color coding of resistors; *solver for inductances; *solver for the skin depth; *added more solutions for liquid resistors; pptools 0.6: *added skin depth calculator (currently based on tabulated data); *added tables in the inductances and resistance calculations. These tables are then using selected interpolations (linear, log, semi-log...) to extract values and return their status (out of tables, ...); *added better tables for CuSO4;
