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 5 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.

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

#5 A string with a range like one of the 4 types above. Example: M1:N2

Note:

The code does not understand a range given as: =M1:N2. The equal sign (=) has to be removed.
