Distribution

This argument allows the user to give the distribution of the polymer as a function argument.

The most important use of this is when calculations are linked.

For example a separation process can be modeled by linking a series of isenthalpic flashes where the composition of each phase is used as input to the next calculation. The distribution will then change for each phase.

There are 4 types of accepted input:

#1 A row with new mass fractions.  The molar masses are taken from the project sheet.

#2 A column with new mass fractions.  The molar masses are taken from the project sheet.

#3 Two rows with a number of columns. Both molar masses and mass fractions are given by user.

#3 Two columns with a number of rows. Both molar masses and mass fractions are given by user.
