Input
=====

Tomcat may take many inputs but most of them
don't need to be changed by the average
user, as such they were given a "standard"
value. The variables an average user might
want to change are listed in Input_TestModBC and are:

* namecase: The name of the machine
* shortname: short name of the machine
* N0: core density [m^-3]
* N1: edge density [m^-3]
* nspeci: number of species present in the plasma
* z: species charge numbers
* a: species mass numbers
* concentr: species concentrations

* ichargeneut: speci where you enforce charge neutrality (most often majority ion)
* iforcechargeneut: boolean forcing charge neutrality computation

* ap: minor radius [m]
* R0: major radius [m]
* B0: Toroidal magnetic field [T]
* IDSHAPE,xkap,del0,delt: machine definitions, a boolean to enable D shape, kappa (elongation), Shafranov shift of the magnetic axis and triangularity

* T0: species core temperature [eV]
* T1: species edge temperature [eV]

* exponn= exponential in density profile
* expont= exponential in temperature profile

* frek: frequency [Hz]

* ntor: toroidal mode number

* xleft/right: start and stop point simulation
* xleftin/xrigthin: inner domain, between xleft and xleftin is a detailed region with high resolution solving, similar for xright and xrightin.

* numLFS: number of elements on the LFS space
  inbetween xright and xrightin
* numHFS: number of elements on the LFS space
  inbetween xleft and xleftin
* zleft/right: Integration interval is from (xleft,zleft) to (xright,zright) 

* icollis= boolean to enable collisions
* colfreq= collision frequency, per species
* iasymp= asymptotic expansion of plasma dispersion function used or not
* ky= wavevector in the y (Z) direction
* IHFS: Antenna at the HFS or not
