JoSIM v2.5 - Update 1: Fixed parameter parsing and pulse command

Changelog

v2.5 (Update 1) - 12/03/2021

• Phase mode is now the standard analysis mode. Produces the exact same results as voltage.
• Trapezoidal method has been replaced by superior 2nd order Gear method.
• JoSIM now internally determines the convention. (-c option removed)
• New progress indicators added. Spawns a seperate non blocking thread.
• New verbose modes. 1: Circuit statistics. 2: 1 + Parameters and evaluated values. 3: 2 + Complete expanded netlist.
• New DC source type. I.e. V01 1 0 DC 5V
• JJ has new IC= parameters that supersedes AREA= but ultimately performs similar model parameter scaling.
• Fixed NOISE source type to have syntax NOISE(AMP TD TSTEP)
• New '.temp' and '.neb' commands for thermal noise analysis
• Transient simulation command now allows PRSTART and PRSTEP commands. .tran TSTEP TSTOP PRSTART PSTEP
• Various memory improvements and overall speed-up
• Reduced output file size.
• Rewrote documentation: JoSIM Documentation
• Various bug fixes
