* miscutils, packaging are subprojects which are depended upon
* configured correspondingly in build.sbt, removed symlinks in src
* defined metadata for build artifact (incl. version)
* updated .gitignore to ignore temp files in subprojects

6d4e97b Add build.sbt to define artifact

* AXI4Lite interface
* flexible ControlRegister class hierarchy: constants, single values,
  virtual registers (callbacks)
* implemented unit test cases
* had to implement Axi4LiteProgrammableMaster for batch testing

* muxes N AXI-MM masters to one AXI-MM slave
* read and write channels are mux'ed independently
* no interruptions during bursts, next schedule on LAST
* address valid is used to signal transfer requests
* may cost up to N-1 cycles latency

* renameSignals on AXI bundle should support prefix and suffix in order
  to accomodate multiple instance of the interface in one module

* configurable sliding window module with AXI DMA backend
* uses AxiFifoAdapter internally to retrieve data from AXI slave
* shifts with Decoupled interface
* generic module for arbitrary bitwidths / data types

* has method to fill AxiSlaveModel with structured data for testing

* moved config params into sealed case class
* unified constructors to use new config object
* added companion object for convenience constructors (backward
  compatible)
* changed constructor calls in unit tests accordingly

* size parameter indicates automatic address wrapping
* no need for resets in between (not always feasible)
* wraps on overflow to current value of `base` input

* new methods allow getter access via address or index
* set method supports writing at address
