PPTools: small but convenient utility for Pulsed Powers

PPtools aims to be a generic toolbox for people working in the Pulsed Powers field. Of course, it won't pretend to provide the kind of capability a full MHD or circuit code would but it should ease your life by providing a few convenient utilities.

Here are some key features of "PPTools":
Solving of RLC circuit: give all parameters but two, solve the two unknowns!
Resistors color coding: enter the color code, read the resistance value! Or enter the resistance you need, then read the closest color code!
Liquid resistors solver: give all parameters but one, solve the unknown!
Inductances calculator: select the geometry, enter the parameters, then read the associated inductance and capacitance! (flux leakage coefficients included, according to Knoepfel calculations)
Skin depth calculator: select the applied signal shape, select the electrodes materials, give all parameters but one, solve the unknown!
Help window describing all the features and giving details about the calculations (in About tab).

What's New:
maximum solubility now accounted for in liquid resistors;
suppressed the unused variables in colorcoding::solve;
class for managing forms=better modularization of the components making the UI;
suffixes like "u, k, M" can be used in all input fields;
suffixes like "u, k, M" now used for formatting the results;
tables assigned once and for all the calculation in the inductance
alculator;
better initial conditions in all solvers but RLC;
more inductances models in the inductance calculator;
more solutions in the liquid resistance calculator;
icones symbolizing the geometries in the inductance calculator (so cute...!);
better handling of warnings and error messages in the inductance calculator;
better convergence of the Newton's method: the solver now knows about some physical caracteristics of the solution it is looking for
(positive value, greater than another field, ...) making the use of the solver on inductance calculations much more successful;
code cleanup;
new icons for the program, for dark backgrounds;
in the skin depth calculator, there is a message displayed if we go out of the tables (because it is currently using tabulated
values).
