1) The initialization now accepts "general" inputs that should apply to each gene. For example, rather than a gene input of [1,100] being interpreted to mean gene 1 hsould be 1 and gene 2 should be 100, it will apply a range of [1,100] to each gene. 2) The initialization now accepts "general" gene_input_types. For example, if the user had a set of index-dependent number values, they could just say ga.gene_input_type = "domain" and the package will propagate that across all genes in the chromosome. The user still has the option of defining the entire array or just defining a specific element if they so choose. For later commits, the general gene_input_type will have to be checked for validity; for example, a string can never be a range. 3) Fixed an issue in the ordering of the initialization function call. 4) Added comments surrounding the signfiicant changes to the initialization. 5) Added example tests to the testing file.

#Example tests
|
|
#Note, the following examples assume a chromosome length of 4.
|
|
#if the test_gene_input is longer than the chromosomes, it will get truncated at the length of the chromosome
|
|
#for example, for chromosomes with length 2, [["left", "right"],[1,100],[5.0,10],[22,"up"]] becomes [["left", "right"],[1,100]]

#if the test_gene_input is shorter than the chromosomes, the remaining elements will be populated with None
