* R/shiny-ui-base.R(txt2tags,combine_tags): Move
  to R/shiny-ui-config.R.

* R/shiny-ui-config.R(get_tags_from_txt): Turn into reactive from
  eventReactive. Will it now execute even when button non-pressed?

(server_conf) <rv$m observer>: Add tag handling.

(server_conf) <mzMLtabCtrl render>: Adapt to new tag handling.

Sorry :)

* R/shiny-ui-base.R(vols,vol_f,volumes): Obsoleted. Removed.

(mk_roots): New function.

* R/shiny-ui-config.R(get_proj_vol,get_proj_path): Obsoleted. Removed.

(server_conf) <shinyFile observers>: Adapt to mk_roots functionality.
<input$switchProjB observer>: Same as above.

* R/shiny-ui-base.R, R/shiny-ui-base.R (rv_lst2lst, lst2rv_lst,
  rev2list, list2rev): rv_lst2lst -> rev2list, lst2rv_lst -> list2rev

* R/shiny-ui-base.R(isol): New function.
  Alias for isolate.

* R/shiny-ui-config.R(rf$initial_mzml): New reactive function.

(input$mzMLB): New observer.

(rv$conf): Updated.

R/shiny-ui-config.R(rf$get_tags_from_txt): New reactive function.

* R/shiny-ui-config.R(rf$get_compounds): New reactive function.

* R/shiny-ui-config.R(input$restoreConfB):

Use load_inputs from the command line way of doing things to read all
the inputs. This way, we have the batteries included.

R/shiny-ui-config.R(server_conf): conf is transformed using
rv_lst2lst, file parsing is fixed and so on.

* R/shiny-ui-config.R <shinyFileChoose observers>: Replace vs with volumes.

* R/shiny-ui-config(fnKnownLCtrl,fnUnkLCtrl,fnSetIdCtrl):
  fnKnownL,fnUnkL,fnSetId buttons.

* R/shiny-ui-config.R<validate>: Change validations of one condition
  to validate1.

* R/mix.R(read_conf): New function.

* R/shiny-ui-base.R(conf2rv_conf): New function.
  In order to save config as yaml function, the reactive form of
  config must be converted to a list.

 (input$restoreConfB): New observer.

* R/shiny-ui-base.R(server_conf), R/shiny-ui-top.R(server): Now that
  we update rv inside server_conf, it must return it in some way.

* R/shiny-ui-base.R(obsrv_e,validate,vol_f): New wrappers.

* R/shiny-ui-config.R(saveConfB): Change default filename and
  filetype.

* R/shiny-ui-config.R(input$saveConfB): New observer.

Because we decided to split the server and UI definitions into
separate "modules", we also needed to create a way for different
modules to exchange their reactive values and functions.

In this regard, each module is going to have two server-like
functions, react_module-name_f and react_module-name_v, which will
define and return reactive functions and objects, respectively. Each
such function is server-like, i.e. it will take input, output and
session arguments. The two remaining arguments are rv and rf, for the
input reactive values and functions.

* R/shiny-ui-config.R(react_conf_v): New function.
  Add conf-related reactive values.

  (react_vonf_f): New function. Add conf-related reactive functions.

  (server_conf): Update observers.

* R/shiny-ui-top.R(server): Adapt to the new concept.

* R/shiny-ui-config.R: New file.
  It will contain everything related to the configuration tab of the
  former shinyUI.R

* R/shiny-ui-top.R: Updated with the config plug-in.

* DESCRIPTION: Updated.
