+ \brief Convert string representation of version identifier to the numerical value.
+ Resulting value can be used for comparison of different versions (lower, higher, equal).
+
+ String representation of the version consists of zero or more components:
+
+ [major[.minor[.release[patchid]]]]
+
+ where
+ - major is version major number
+ - minor is version minor number
+ - release is version release number
+ - patchid is a version dev identifier which is one of the following
+ * 1 letter optionally followed by 1 or 2 digits, e.g. "a" for "alpha", "b1" for "beta 1"
+ * "rc" optionally followed by 1 or 2 digits, e.g. "rc1" for "release candidate 1"
+ * "dev" for development version (note: 7.4.0dev > 7.4.0, 7.4.0dev < 7.4.1, 7.4.0dev < 7.4.0a1)
+
+ If version string does not include any component or has invalid format, the function returns 0.
+
+ Examples:
+ 1.0 - version 1.0
+ 1.2.3a - version 1.2.3 alpha
+ 3.3.3b1 - version 3.3.3 beta 1
+ 7.4.0rc1 - version 7.4.0 release candidate 1
+ 7.4.0dev - dev version, i.e. future version 7.4.1 (or 7.5.0)
+
+ \param version string representation of version
+ \return numerical identifier of the version
