In rSHAPE: Simulated Haploid Asexual Population Evolution

This function querries if a suite of genotypes exist within the fitness landscape database.

  tmp_refTables, maxHamming = getOption("shape_max_numMutations"),
  tmp_tableSplit = getOption("shape_db_splitTables"),
  tmp_genomeLength = getOption("shape_genomeLength"),

`tmp_possibleNeighbours`	This is a vector of all possible mutants that we're trying to querry within the fitness landscape database.
`tmp_focal_numMuts`	This is the number of mutations in the focal genotype, it controls - along with other parameters - what tables of the fitness landscape database are querried.
`tmp_refTables`	This is the a vector of named tables that exist within the fitness landscape. It can not be passed in which case the database at tmp_genCon is querried for this information.
`maxHamming`	The maximum number of sites that could be changed by mutation of the tmp_focalGenotype.
`tmp_tableSplit`	This is a logical which controls if the tables which report on all genotypes with X mutations should be forced into a single table or it SHAPE is allowed to split them into multiple tables.
`tmp_genomeLength`	The length of the genomes, or number of mutable sites/positions, being simulated.
`tmpDirection`	This is a logical which controls if reversions are allowed (ie: if TRUE sites can revert from mutated to WT)
`tmpRange_numMuts`	This is the range of number of mutations which a mutant neighbour may posses. If not supplied that will be calculated in line via other parameters passed to the function.
`tmp_genCon`	This is the filepath for the database file that contains the fitness landscape information.
