Return new instances without caching them

[ranapat]

Currently all instances that are get or inject are auto-cached in memory. Maybe it will be useful to add method to get an instance without keeping it - the same as making new instance alone.

Reason - others do it, maybe there is a reason why Reason I can think of as of now - if "named template configurations are implemented".

Example:

• We generate template named "wow1" that is Class.class with [parameters]
• Getting same instance of this class is possible with get(wow1) or inject(wow1)
• Getting new instance without caching is possible with something like new(wow1)

If approach such issue - concept of named templates shall be also implemented.

the new method will be called unique
