Dexie.version

Static property containing the version number of the Dexie library as a decimal number that is comparable.

Dexie.version is the number representation of Dexie.semVer calculated by:

Dexie.version = Dexie.semVer.split('.')
  .map(n => parseInt(n))
  .reduce((p,c,i) => p + (c/Math.pow(10,i*2)));

Dexie.semVer	Dexie.version
"1.0.0"	1.0
"1.0.1"	1.0001
"1.1.0"	1.01
"1.3.4"	1.0304
