bower dependency version expression

Bower uses the semver range to match versions.
Common version area expressions:
Comparator: < > <= >= =
Range: 1.2.3 - 2.3.5
Wildcard: 1.2.* Match: Greater than 1.2.0 Less than 1.3.0
Wave Range: ~1.2.3 Match: Greater than the current version, less than the last digit +1, in this case greater than 1.2.3 less than 1.3.0
Caret range: ^1.2 Match: greater than the current version, less than the first non-zero value from the left +1, this Example greater than 1.2 less than 2.0
