Copy-paste into ~/.bash_completion (or ~/.bashrc) to enable basic bash completions for Conda. Assumes that you have Miniconda3 installed at ~/miniconda3.

• conda activate <TAB> for locally installed Conda envs (directories in ~/miniconda3/envs/).
• completions for most commands in Conda v4.7.11 (conda <TAB> and conda env <TAB>)
