<pre>Creates a new variant.
Args:

"A String",

"end": "A String", # The end position (0-based) of this variant. This corresponds to the first base after the last base in the reference allele. So, the length of the reference allele is (end - start). This is useful for variants that don't explicitly give alternate bases, for example large deletions.
"calls": [ # The variant calls for this particular variant. Each one represents the determination of genotype with respect to this variant.
{ # A Call represents the determination of genotype with respect to a particular variant. It may include associated information such as quality and phasing. For example, a Call might assign a probability of 0.32 to the occurrence of a SNP named rs1234 in a call set with the name NA12345.
