The profile is a complete set of strings assigned to set of 26 symbols "a" to "z".
If the symbol is not assigned, the string is void.

Generally, there are two types of symbols - variables and functions.

 Variables:
  defined symbols assigned with their exact initial value, without any dependence on other symbols.
Examples:
  x=3
  y=sqrt(2)
  z=sin(pi/4)

  Functions:
  defined symbols assigned with mathemahical rule descripting their dependence on other symbols.
Examples:
  a=x
  b=2*sin(x+y)
  c=sqrt(sqr(sin(x))+sqr(sin(y)))

 The symbol is classified as a variable or as a function automatically by Syntan.
 The instant values of variables are not a part of the profile.
 The profile can be saved to the disk and load from it back. It is a simple text file and it can be assigned by name before saving. The standard and registered extension of the profile files is .SYN.
 The specific part of the profile forms a set of parametres describing the state of application´s settings in the instant of saving. It is the angle measurment unit (rad, deg, grad), the selected symbol, the position of the knob and so on.
