create_data()
simulates an alphabetr sequencing experiment by sampling
clones from a clonal structure specified by the user. The clones are
placed on a frequency distribution where a fixed number clones represents
the top proportion of the population in frequency and the other clones
represent the rest of the population in frequency. Different error models
and different sampling strategies can be simulated as well.

dist = "linear", numb_cells)

TCR 
The specified clonal structure, which can be created from

plates 
The number of plates of data. 
error_drop 
A vector of length 2 with the mean of the drop error rate and the sd of the drop error rate. 
error_seq 
A vector of length 2 with the mean of the inframe error rate and the sd of the inframe error rate. 
error_mode 
A vector of two strings determining the "mode" of the error
models. The first element sets the mode of the drop errors, and the second
element sets the mode of the inframe errors. The two modes available are
"constant" for a constant error rate and "lognormal" for error rates
drawn from a lognormal distribution. If the mode is set to "constant" the
sd specified in 
skewed 
Number of clones represent the top proportion of the population
by frequency (which is specified by 
prop_top 
The proportion of the population in frequency represented by
the number of clones specified by 
dist 
The distribution of frequency of the top clones. Currently only "linear" is available. 
numb_cells 
A two column matrix determining the sampling strategy of the experiment. The first column represents the number of cells per well, and the second column represents the number of wells with that sample size. The sum of column 2 should equal 96 times the number of plates. 
A list of length 2. The first element is a matrix representing the data of the alpha chains, and the second element is a matrix representing the data of beta chains. The matrix represents the sequencing data by representing the wells of the data by rows and the chain indices by column. Entry [i, j] of the matrix represents if chain j is found in well i (yes == 1, no == 0). e.g. if alpha chain 25 is found in well 10, then [10, 25] of the alpha matrix will be 1.
