Bit build should build dependency tree

[marcusfroling]

Description

Bit build should also build dependency tree. When working on multiple components, it is now necessary to build all components manually. E.g, say you have 3 components A,B and C. When modifying component A which has dependencies A->B->C, it is necessary to also manually build component B in order to have these changes in component C.

Describe the solution you'd like

When working on multiple components, running bit build should also build all components that are depending. This could be done by default or by having a flag, e.g --build-dependencies

@marcusfroling Thanks.
Right now it's in the compiler writer hand.
There is a flag the compiler can specify to tell bit to do this.
In the upcoming version, this build chain will be much smarter. we call it a network of components and we will provide many APIs to make the proper network build.

Thanks for the reply @GiladShoham , good to know you are working on improving the build chain.
Is there any date set for this version release? Also, is there any documentation on available flags for compilers?

[GiladShoham]

There is no exact date. (I believe it will take few weeks, but can't guarantee)
