Demonstrates the DeleteColumnByName method. Rust

// We have the following CSV...

// permalink,company,numEmps,category,city,state,fundedDate,raisedAmt,raisedCurrency,round
// lifelock,LifeLock,,web,Tempe,AZ,1-May-07,6850000,USD,b
// mycityfaces,MyCityFaces,7,web,Scottsdale,AZ,1-Jan-08,50000,USD,seed
// flypaper,Flypaper,,web,Phoenix,AZ,1-Feb-08,3000000,USD,a
// infusionsoft,Infusionsoft,105,software,Gilbert,AZ,1-Oct-07,9000000,USD,a
// gauto,gAuto,4,web,Scottsdale,AZ,1-Jan-08,250000,USD,seed
