 Description: Add-on package to the 'airGR' package that simplifies its use and is aimed at being used for teaching hydrology. The package provides 1) three functions that allow to complete very simply a hydrological modelling exercise 2) plotting functions to help students to explore observed data and to interpret the results of calibration and simulation of the GR ('Génie rural') models 3) a 'Shiny' graphical interface that allows for displaying the impact of model parameters on hydrographs and models internal variables.

 #### New features
 
-- the <code>ShinyGR()</code> interface, can now run on monthly time series, using the GR2M model
+- the <code>ShinyGR()</code> interface, can now run on monthly time series, using the GR2M model. So, now 'airGRteaching' depends on the version of 'airGR' >= 1.4.3.87)
 - in the <code>ShinyGR()</code> interface, there is a new tab panel that shows a summary sheets of basin if the name of the dataset contains the code station  (8 characters : 1 letter and 7 numbers) of the Banque Hydro French database (so it is available only for the dataset of this database)
